Thirty-six were fallers and 18 were non-fallers. Fatigue was assessed by the Iowa Fatigue Scale. Excessive daytime sleepiness was assessed by the Epworth Sleepiness Scale, and depressive symptomatology was assessed by the short-form Center for Epidemiologic Studies Depression Scale. &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; Compared to non-fallers, fallers had more severe disability, greater general physical fatigue (p = 0.024), lower energy levels (p = 0.042) and less productivity (p = 0.007). Fallers had more depressive symptomatology than the non-fallers (p = 0.01). Excessive daytime sleepiness was not different between the two groups (p = 0.695). &lt;b&gt;&lt;i&gt;Conclusions:&lt;\/i&gt;&lt;\/b&gt; Individuals with PD who fell had more severe motor and non-motor symptoms than those who did not fall. These non-motor symptoms included physical fatigue, energy, productivity and depressive symptomatology.<\/jats:p>","DOI":"10.1159\/000335877","type":"journal-article","created":{"date-parts":[[2012,5,3]],"date-time":"2012-05-03T08:12:56Z","timestamp":1336032776000},"page":"326-330","source":"Crossref","is-referenced-by-count":26,"title":["The
